The greenhouse effect and climate change

Text

Information sheet:
The heat radiated by the earth does not reach outer space unimpeded; some of it is absorbed and reflected in the earth's atmosphere. Without this effect, we would be living in a permanent ice age on earth.

This information clears up the prejudice that the greenhouse effect is basically something negative. Without the natural greenhouse effect, life on earth would not be possible at all. The gradual increase in global warming, however, is the result of an anthropogenically caused greenhouse effect. The differences are explained. In addition, the fundamental physical facts are presented, i.e. the radiation balance and the radiation absorption of molecules.

Information and ideas:
You can have your students look for possible ways of reducing the anthropogenically enhanced greenhouse effect in the short, medium or long term. Political, economic and personal aspects can be discussed separately.
